Which of the following statement is not correct for Butan-2-ol?
- A It exists as a pair of non-superimposable mirror images
- B It is optically inactive
- C It is chiral
- D It has one stereocentre
Answer & Solution
Correct Answer
(B) It is optically inactive
Step-by-step Solution
Detailed explanation
Butan-2-ol is a chiral molecule due to the presence of a stereocentre at carbon 2. Chiral molecules are optically active (unless they are a racemic mixture). Therefore, the statement "It is optically inactive" is not correct.
